Abstract
BACKGROUND AND PURPOSE MR imaging with sedation is commonly used to detect intracranial traumatic pathology in the pediatric population. Our purpose was to compare nonsedated ultrafast MR imaging, noncontrast head CT, and standard MR imaging for the detection of intracranial trauma in patients with potential abusive head trauma. MATERIALS AND METHODS A prospective study was performed in 24 pediatric patients who were evaluated for potential abusive head trauma. All patients received noncontrast head CT, ultrafast brain MR imaging without sedation, and standard MR imaging with general anesthesia or an immobilizer, sequentially. Two pediatric neuroradiologists independently reviewed each technique blinded to other modalities for intracranial trauma. We performed interreader agreement and consensus interpretation for standard MR imaging as the criterion standard. Diagnostic accuracy was calculated for ultrafast MR imaging, noncontrast head CT, and combined ultrafast MR imaging and noncontrast head CT. RESULTS Interreader agreement was moderate for ultrafast MR imaging (κ = 0.42), substantial for noncontrast head CT (κ = 0.63), and nearly perfect for standard MR imaging (κ = 0.86). Forty-two percent of patients had discrepancies between ultrafast MR imaging and standard MR imaging, which included detection of subarachnoid hemorrhage and subdural hemorrhage. Sensitivity, specificity, and positive and negative predictive values were obtained for any traumatic pathology for each examination: ultrafast MR imaging (50%, 100%, 100%, 31%), noncontrast head CT (25%, 100%, 100%, 21%), and a combination of ultrafast MR imaging and noncontrast head CT (60%, 100%, 100%, 33%). Ultrafast MR imaging was more sensitive than noncontrast head CT for the detection of intraparenchymal hemorrhage (P = .03), and the combination of ultrafast MR imaging and noncontrast head CT was more sensitive than noncontrast head CT alone for intracranial trauma (P = .02). CONCLUSIONS In abusive head trauma, ultrafast MR imaging, even combined with noncontrast head CT, demonstrated low sensitivity compared with standard MR imaging for intracranial traumatic pathology, which may limit its utility in this patient population.

Abstract
Past research has identified a positive relationship between life-event stress and football injuries, but research in other sports has yielded more ambiguous results. It seems, then, that the relation of life stress and injury may be sport-specific and that different sports must be studied separately before such a relationship is assumed. The present investigation examined the relationships among life-event stress, coping skills, social support, and injuries of male and female high school basketball players. Contrary to the hypothesis, the number of days missed due to injury was not significantly related to life-event stress. As expected, the injury measure was negatively correlated with both the coping-skills and social-support variables, but these correlations did not reach statistical significance. Recommendations for research are discussed.

Abstract
This study evaluated the abilities of various plant species to act as bio-monitors for environmental uranium (U) contamination. Vegetation and soil samples were collected from a U processing facility. The water-way fed from facility storm and processing effluents was the focal sample site as it represented a primary U transport mechanism. Soils and sediments from areas exposed to contamination possessed U concentrations that averaged 630 mg U kg(-1). Aquatic mosses proved to be exceptional accumulators of U with dry weight (dw) concentrations measuring as high as 12,500 mg U kg(-1) (approximately 1% of the dw mass was attributable to U). The macrophytes (Phragmites communis, Scripus fontinalis and Sagittaria latifolia) were also effective accumulators of U. In general, plant roots possessed higher concentrations of U than associated upper portions of plants. For terrestrial plants, the roots of Impatiens capensis had the highest observed levels of U accumulation (1030 mg kg(-1)), followed by the roots of Cyperus esculentus and Solidago speciosa. The concentration ratio (CR) characterized dry weight (dw) vegetative U levels relative to that in associated dw soil. The plant species that accumulated U at levels in excess of that found in the soil were: P. communis root (CR, 17.4), I. capensis root (CR, 3.1) and S. fontinalis whole plant (CR, 1.4). Seven of the highest ten CR values were found in the roots. Correlations with concentrations of other metals with U were performed, which revealed that U concentrations in the plant were strongly correlated with nickel (Ni) concentrations (correlation: 0.992; r-squared: 0.984). Uranium in plant tissue was also strongly correlated with strontium (Sr) (correlation: 0.948; r-squared: 0.899). Strontium is chemically and physically similar to calcium (Ca) and magnesium (Mg), which were also positively-correlated with U. The correlation with U and these plant nutrient minerals, including iron (Fe), suggests that active uptake mechanisms may influence plant U accumulation.

Abstract
Inferior temporal cortex of squirrel monkeys consists of caudal (ITC), intermediate (ITI), and rostral (ITR) subdivisions, possibly homologous to TEO, posterior TE, and anterior TE of macaque monkeys. The present study compared visual learning in squirrel monkeys with ablations of ITC; ITI and ITR (group ITRd); or ITI, ITR, and more ventral cortex, including perirhinal cortex (group ITR+), with visual learning in unoperated controls. The ITC monkeys had significant impairments on pattern discriminations and milder deficits on delayed non-matching to sample (DNMS) of objects. The ITRd monkeys had deficits on some pattern discriminations but not on DNMS. The ITRd monkeys were significantly impaired on DNMS and some pattern discriminations. These results are similar to those found in macaques and support the proposed homologies.

Abstract
The anxiety scores of 23 left-handed, 12 mixed-handed and 35 right-handed college students were compared with the result that right-handers were significantly less anxious then both the left and the mixed-handed groups (which did not differ statistically). Since these data appear to be unique, generalizations from them was thought to be premature.

Abstract
BACKGROUND Many potential lung donors are excluded on the basis of a positive donor gram stain (DGS). We examined the association between a positive DGS and the probability of post-operative recipient pneumonia in the first 30 days. METHODS Ninety lung transplants (80 with a non-septic pre-transplant diagnosis) from 60 consecutive donors were evaluated for post-operative pneumonia (defined as a compatible clinical syndrome with fever, leukocytosis, chest X-ray abnormalities or histologic evidence obtained by transbronchial biopsy). DGS, white blood cell quantity, CXR and PaO(2)/FIO(2) (P/F) ratio were compared with immediate and 24-hour P/F ratio, length of mechanical ventilation and incidence of pneumonia. All recipients received standard prophylactic anti-bacterial coverage. Patients not surviving 30 days (n = 3) were excluded from this study, but none had evidence of pneumonia either by bronchoalveolar lavage (BAL), transbronchial biopsy or autopsy. RESULTS Fourteen (16%) of our 87 recipients developed pneumonia in the first 30 days after transplant. Of the 43 patients with a positive DGS, 5 (12%) developed pneumonia, compared to 9 of 44 (20%) with a negative DGS (p = 0.26). The mean post-operative P/F ratio (315 +/- 47 with a positive DGS, p = 0.3) and length of mechanical ventilation (2 days in each group) did not differ significantly between the negative and positive DGS groups. CONCLUSIONS In the current era of lung transplantation, DGS does not predict the development of early post-operative pneumonia and does not affect oxygenation or duration of mechanical ventilation; therefore, its role should be diminished when judging donor lung suitability.

Abstract
OBJECTIVE To determine the frequency of court appearance by pediatricians evaluating child abuse and neglect cases and to identify case characteristics associated with actual court appearance or case adjournment. DESIGN Retrospective review of subpoenas received between 1995 and 1999 for child maltreatment cases personally evaluated by 2 pediatricians during the years 1995 to 1998. Information was collected regarding patient age, gender, race/ethnicity, type of suspected maltreatment, date of evaluation, date of subpoena, type of court hearing, whether the pediatrician actually testified in court, and legal outcomes. Case characteristics were compared between pediatricians and were used to predict physician appearance and case continuance or adjournment in logistic regression models. RESULTS Four hundred forty-five subpoenas concerning 260 patients were received. Although significant differences were noted between the pediatricians in type of abuse, no differences were found in patient age, gender, ethnicity or legal outcomes. The pediatricians received subpoenas in <15% of child maltreatment cases, and <5% of children seen resulted in the physician being required to actually appear in court. No case characteristics significantly predicted court appearance or case continuance or adjournment. CONCLUSIONS Although pediatricians are sometimes subpoenaed to appear in court to explain the medical evaluation and the needs of the child in cases of child abuse and neglect, most court cases were continued, adjourned, or settled before physician testimony. Most subpoenas did not result in the pediatrician going to court, and it is unclear which child factors may predict court involvement. Pediatricians can take steps to minimize (but not eliminate) the potential dissatisfaction and inconvenience associated with receiving and responding to subpoenas in child maltreatment cases.

Abstract
The study was designed to extend inquiry on adult attachment style to include the variable of personal stamina. The data were derived from an anonymous survey administered to 163 college students (82 women and 81 men) in introductory psychology classes. Attachment style was measured by the Close Relationship Questionnaire, based on a four-category scheme suggested by Bartholomew. Stamina was evaluated with a self-report scale developed by R. A. Hicks. The pattern of statistically significant differences (p < .001) in the relative frequency with which respondents self-identified with descriptions of each of the four attachment styles on the questionnaire diverged somewhat from those reported previously. Respondents who identified themselves as most accurately described by the questionnaire's alternative defined as characterizing secure attachment had significantly higher stamina scores than did those who self-endorsed the fearful or preoccupied alternatives in that categorical measure. No other pairwise comparisons of stamina scores were statistically significant. The results provide preliminary support for the hypothesis that secure attachment is more facilitative of personal stamina than are insecure styles. Methodological limits on inferences and corresponding alternative interpretations, the potential effectiveness of defensive suppression of the attachment system in dismissing-avoidant adults, and directions for research are discussed.

In this study, we measured the relationship between the consistency of hand use and three symptoms of insomnia, i.e., delayed sleep onset, frequent awakenings during sleep, and trouble returning to sleep after an awakening. For each of these insomnia-related symptoms, university students who were classified as inconsistent in the use of their hands (n = 30) were significantly more likely to report problems than their consistent hand-use peers (n = 30). These data were discussed both in relation to the literature on handedness classification and sleep problems and the emerging literature on consistency of hand use and health-related problems.

Abstract
We examined relationships between consistency of hand use and falling in groups of right-handed university undergraduates who were either consistent (n = 45) or inconsistent (n = 32) in the use of their hands. A scoring procedure developed for the Briggs-Nebes Handedness Scale permitted us to classify individuals as consistent or inconsistent in the use of their hands. The inconsistent group was 2.81 times more likely to have experienced frequent falls during the last 12-mo. period and was 1.64 times more likely to rate themselves higher on proneness to falling. These data suggest that inconsistent hand use may be a sign of a developmental inconsistency in motor coordination.

Abstract
In this study, we examined the relationship between the consistency of hand use and the self-reported incidence of accidents with injuries which required medical care in groups of university students (n = 23 for each group). To do this, we adopted a scoring procedure for the Briggs-Nebes Handedness Scale that permitted us to classify individuals as consistent or inconsistent in the use of their hands. We observed that the inconsistent group was 6.12 times more likely to have experienced accidents with injury that required medical care than the consistent group. These data have implications for the literature on handedness classification and accidents. Collectively, these limited data underscore the need to pay attention to the consistency of hand use in research on handedness, health, and longevity.

Since only one of the 21 possible statistical tests computed barely reached statistical significance, there is no meaningful relationship between handedness and stress-related health problems.

To consider the relationships among Type A-B behavior, gender, and specific types of nightmares, 780 university undergraduates were tested with Glass' version of the Jenkins Activity Survey and the Spadafora and Hunt Dream Types Survey which included the critical nightmares (fantastic nightmares, posttraumatic nightmares, and night terrors). Relative to students classified as Type B, those classified as Type A were significantly more likely to report experiencing certain types of nightmares, i.e., fantastic and posttraumatic nightmares. We also observed that women reported significantly greater frequencies of all types of nightmares than men. Possible reasons for these differences were discussed.

Abstract
Medical, social service and coroner reports were reviewed for 14 cases of fatal child abuse and neglect identified at a children's hospital from 1988-1992. Twelve cases involved physical abuse and two neglect. The median age was 6.5 months (range 24 days to 3 years). Six families (43%) had prior protective service involvement; however, four of the referrals involved a sibling. Only two of 12 physical abuse victims had a history of a prior suspicious injury. Clinical and postmortem findings are presented. The cause of death in all physically abused patients was blunt impact head injury; one also had contributing intraabdominal injuries. Ten cases were ruled due to homicide; 12 have come to legal closure resulting in nine felony convictions. These findings emphasize the role of blunt impact brain injury in fatal child abuse cases. Two findings have significant implications for prevention: (a) the paucity of injuries recognized prior to the fatal event, and (b) among families known to child protection agencies the focus was not the fatally injured child.

Abstract
The relationship of a ruminating and a distracting response style upon severity of depression and on gender were investigated. The Ways of Coping Questionnaire was modified to include ruminating and distracting scales and administered to 91 undergraduate students who also completed the Beck Depression Inventory. It was hypothesized that (a) regardless of gender, people who ruminate would have greater rated severity of depression than people who distract themselves; (b) women ruminators would show higher rated severity of depression than women distractors; and (c) female and male ruminators would show the same ratings on severity of depression. A set of t ratios was computed for mean differences between the groups. An analysis of variance for response style x gender was also done with the women and men classified as ruminators. The results conformed to the predictions for women but not for men.

Abstract
In support of the argument that left-handedness is a marker for decreased survival fitness, in 1991 Coren and Halpern gave considerable weight to the results of their 1988 study in which right-handed baseball players were described as having lived about eight months longer than their left-handed peers. In their 1993 unsuccessful attempt to replicate this study, Fudin and colleagues cited certain difficulties with the sources of these data that led them to recommend a comprehensive third study which included only reliable data from the two current editions of the major sources of information on Major League baseball players, i.e., the 1993 editions of The Baseball Encyclopedia and Total Baseball. Following this suggestion, we measured the life spans of all baseball players, i.e., right-, left-, and mixed-handed players, for whom reliable data were available (N = 5441) and found that the relationship between handedness and longevity was not significant. Unlike Halpern and Coren we noted that right-handed players could be described as having lived about eight months less than their left-handed peers.

Abstract
As a test of the hypothesis that eye color is related to reactivity, we measured the relationships between scores on the Arousal Predisposition Scale and two measures of eye color. Our data did not support this hypothesis.

Abstract
The estimates of the incidence of snoring in adults that have been provided by four epidemiological studies vary from 16-89% of the population. Collectively, these data are completely confounded by country of origin and thus may reflect cultural differences that contribute to snoring. While the etiology of snoring is not fully known, speculation has focused on gender and age as primary factors that contribute to this behavior. Within the limitations imposed by the designs of these four studies, we compared the relative strength of the relationships between snoring and gender, age, and culture. These analyses suggest that certain variables associated with cultures appear to be more salient than both gender and age, as determinants of snoring.

Abstract
In an attempt to rationalize conflicting sets of data from earlier studies, groups of Type A- and Type B-classified university students were asked to respond to a sleep habits questionnaire that included the items of the Coren Insomnia Scale. As was the case in two earlier studies, we found significant but weak evidence from the Coren scale only that Type A-scoring students experience more sleep problems than Type B scorers. We also found, as in a recent study, a sharp increase in sleep problems among all the students sampled from the frequencies reported by similar groups in 1982.

Abstract
As evidence for the hypothesis on the claim of reduced longevity for left-handers, Coren in 1989 reported data which suggested that left-handers were 1.89 times more likely to report injuries which required medical attention. This left-handed group included both left- and mixed-handed individuals. To clarify the results of his study, we repeated in part Coren's study but defined handedness so that groups of right-, mixed-, and left-handed individuals were considered. In contrast to Coren's data, we found that right- and left-handers did not differ significantly in the frequency with which they reported having experienced accidents with injury and that mixed-handers reported being significantly more likely to have had an injury-accident than either right- or left-handers. These data underscore the need to consider mixed-handedness as a separate group in studies of this type.

Abstract
A two-year, eight-month-old boy was diagnosed clinically with perianal warts and treated with topical 5-Fluorouracil, with subsequent resolution of the lesions. The child disclosed sexual abuse, and subsequent physical abuse was also documented. Attempts to identify the perpetrator have been hampered by the child's young age and resolution of the skin lesions. The forensic implications of this case are discussed.

Abstract
To test the conclusion of a recent study that snoring and disturbing dreams are strongly associated, 199 university undergraduates responded to a questionnaire that assessed their level of snoring and the frequency with which they experienced fantastic nightmares. Contrary to data provided by this recent study, we did not find a significant relationship between snoring and disturbing dreams. Some possible reasons for the discrepancy between these data sets were considered.

Abstract
Cigarette smoking has been associated with delayed sleep onset and diminished sleep duration, primarily on the bases of responses to one-shot questionnaires. This study used a survey format of daily diaries to observe sleep quality. 29 smokers were matched for age, ethnicity, and gender with 29 nonsmokers. Both groups recorded information on cigarette, alcohol, caffeine consumption, daily stress, and sleep quality. While the results showed that smokers were more likely to experience poor sleep than nonsmokers, these data are difficult to interpret because smokers also used significantly greater amounts of alcohol and caffeine.

Abstract
Ten years ago we reported that Type A scoring students were twice as likely as their Type B peers to report sleep problems. In an exact 1992 replication of that study, no Type A-B differences in the frequency of self-reported sleep problems were observed; however, the over-all incidence of sleep problems among the 753 college students had increased substantially.

Abstract
The relationship between arousability, as measured by the Arousal Predisposition Scale, and bruxism was computed for groups of 41 male and 75 female university undergraduates as a further test of the hypothesis that bruxism is a stress-linked disorder. Contrary to our prediction, arousability was not related to bruxism in men and the relationship between these variables for women was significant but relatively weak. When considered with other studies, these data provide a clearer focus for further study of the stress-bruxism hypothesis.

Abstract
Changes in the consistency of self-reported sleep habits within two large samples of 763 and 782 college students were assessed for 1978 and 1992. Noteworthy changes over the 14-yr. period included significant decreases in the percentage of students who claimed stable (> or = 5-year) sleep-duration habits and the percentage reporting satisfaction with their sleep.

Abstract
We compared the frequencies of Asian and Caucasian women who were classified by their responses to the EAT-26 scale as having eating problems. We noted that relative to their Asian peers, our sample of Caucasian women was 5.5 times more likely to score above the cut-off score for eating problems on this test. Two earlier studies which had reported opposite results for Asian and Caucasian women were discussed and reevaluated in the context of our data.

Abstract
Coren's Arousal Predisposition Scale was validated against 249 college students' self-ratings of stress-related physical symptoms and an item that assessed general level of health. As we predicted, the 126 high-arousability subjects were substantially higher in mean stress-related symptoms score and lower in general health than the 123 peers low in arousability. These data suggest that the Arousal Predisposition Scale may be a useful instrument in the study of human stress.

Abstract
Using several measures of sexual activity, 24 male and 30 female Sprague-Dawley rats were subjected to a pretreatment test and 3 posttests (immediate and Recovery Days 4 and 7) following REM sleep deprivation in a water tank. With careful controls, sexual activity was not significantly affected by the sleep treatments. Data do not support motivational hypotheses.

Abstract
Of 334 undergraduates, 152 scoring greater than or equal to 8 were classified as Type A and 182 scoring less than 8 as Type B. The groups did not differ in attitudes toward leisure activity, but Type A scorers claimed to spend significantly more time weekly in leisure activities than Type B scorers. This suggests Type A people live more intensely relative to type B scorers.
